Distances from NON-combustible materials:
To conform with building regulations the fireplace recess walls should be at least 200mm thick or each rear
leaf at least 100mm thick in the case of a cavity wall at the rear. If these dimensions are not met further
protection for any combustible materials must be provided. The walls of the fireplace recess and the hearth
must be made of non-combustible material.
Hearths:
Heat Design stoves require a 125mm thick non-combustible constructional hearth beneath them to protect
the building, this can include any solid non-combustible floor. A non-combustible superimposed hearth
forming an apron of at least 225mm at the front of the stove and 150mm on either side must also be
provided. The superimposed hearth must not be less than 12mm thick and must have a clearly defined edge
(change of level) to discourage placing of any combustible materials on or partially over it.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the existing construction
does not meet this requirement, suitable measures (e.g. load distributing plate) should be provided to achieve
it.
Commissioning and Handover
Upon completion of the installation, allow a suitable period of time for any fire cement and mortar to dry
out. A small fire may then be lit and checked to ensure the smoke and fumes are taken from the stove up the
chimney and emitted safely to atmosphere.
Advise the customer not to run the stove at full output for at 3 – 4 days. Explain that the stoves can provide
much more or less than their rated heat outputs depending upon how they are burnt and fuels and fuel loads
used.
On completion of the installation and commissioning, ensure that the operating instructions and operating
tools (including glove) for the stove are left with the customer. You must be sure to advise the customer on
the correct use of the appliance with the fuels likely to be used on the stove and warn them to use only the
recommended fuels for the stove.
Advise the user on what to do should smoke or fumes be emitted into the room from the stove – see
Safety
Notes
section. The user should be warned that they MUST use a suitable fireguard in the presence of
children, aged and/or infirm persons.
